10 Claims. (Cl. 36-36) This invention relates to heels for shoes, boots and other footwear, and more particularly to new and useful improvements in rubber heels for mens shoes.

A principal object of the present invention is to provide a rubber heel which is readily applied to the heel of a shoe and which is securely held in position thereon.

Other objects and advantages of the invention will be apparent from the description thereof to follow taken in connection with the accompanying drawings in which- Fig. l is a fragmentary side elevational view of a shoe with a heel embodying one form of my invention applied thereto.

Fig. 14 is a vertical sectional view taken on the plane of the line ltd-14 of Fig. 13.

Fig. 15 is a detail view taken on the plane of the line 15-45 of Fig. l3 and looking in the direction of the arrows.

Referring now to the drawings in detail and particularly to Figs. 1 to 9, inclusive, showing the first form of the invention, in Fig. 1 there is shown a fragment of a mans shoe comprising an upper 21 and an outer sole 22 having a heel portion 23. A heel 24 made in accordance with the present invention is mounted on the heel portion 23 of the shoe.

The heel 24 comprises a thick body 25 of rubber. Embedded in the body 25 of the rubber heel there is a frame 26 (see Fig. 6) formed of fiat stainless steel and consisting of an outer frame member 27 of substantially horse-shoe shape and an inner frame member 28 of similar shape. The frame members are joined together midway their ends and held in spaced relation by a double headed rivet 29, the free ends of the frame members being each formed with aligned slots. A flat strip or plate 30 extends across the space between said free 2,730,820 Patented Jan. 17, 1956 ends and through said aligned slots and disposed perpendicularly to the frame members and is secured in any suitable manner. The plate 30 extends laterally beyond the ends of the outer frame member 27 as shown in Fig. 6. Another plate 31 similar in length to plate 30 but of lesser width is spaced forwardly of plate 30 and is rigidly connected thereto by a pair of spaced plates 32, 32, plate 31 extending through aligned slots in the inner end of the plates 32, 32 and plate 31 extending through similar aligned slots in the outer end of said plates 32, 32. The plates 32, 32 are fastened to the plates 30 and 31 in any suitable manner.

Frame 26 is embedded in the material of the body 25 preferably by placing the frame in a. mold and pouring the molten rubber forming the body of the heel over the frame so that the molten rubber will be bonded to the frame, with a narrow layer of rubber of approximately A above the upper edge of the frame members 27 and 28, and with a thick layer of approximately below the lower edges thereof as shown in Fig. 3. The plates 30 and 31 are sufficiently long to extend beyond both sides of the body 25 of the heel and pivotally mounted on the extending ends thereof in slots 35 in the ends of plate 30 and in similar slots in the ends of plate 31 there are clamping devices 37 and 38.

The clamping devices are similarly constructed and each comprises a substantially triangular-shaped body 4t) of stainless steel. The body portion 40 is slightly curved transversely to conform to the curvature of the body 25 of the heel 24 and is formed with a flat inwardly extending flange 41 which slants slightly downwardly. Depending from the apex portion of the body 40 is an in tegral narrow strap portion 42 turned upon itself midway its ends and extending upwardly therealong forming a looped bearing portion 43 and a curved finger portion 44 overlapping the strap portion 42. A pivot pin 45 extends through the looped bearing portion 43 with its ends projecting outwardly thereof at both ends. The strap portion with its curved finger portion 44 extends loosely through its respective slot 35 in the plate 30 or plate 31, with the pivot pin 45 disposed therebelow.

A locking latch indicated generally at 46 is pivotally supported by the pin 45. The latch comprises a finger 47 having perforated ears or wings 48 at its inner end through which loosely passes the pin 45.. The inner end of each ear 48 is cut at an acute angle to the plane of the finger 47 producing a pointed inner end 49 on each ear. The free end of the linger 47 is curved inwardly.

The heel 24 is applied to the heel portion 23 of the shoe and initially fastened thereto by a coating of adhesive 50 on the outer surface of the heel portion 23. In accordance with the present invention, the heel is also secured to the shoe by the clamping devices 37 and 38. In order to provide a soft, yieldable and sure gripping surface for the clamping devices, the heel portion 23 of the'shoe is preferably cutaway at each side of the shoe as indicated at 51 and a strip of felt 52 inserted in said cutaway portion between the heel portion 23 and the upper 21 of the shoe.

When the heel is applied to the heel portion 23 and secured by adhesive, the clamping devices are in open inoperative position as shown in Fig. 4, with their flanges 41 slightly above the inner surface of the heel portion 23. The finger 47 of each latching device 46 is then swung inwardly around its pivot pin 45 thereby swinging the ears 48 around counterclockwise as viewed in Fig. 4, the edges of the ears carnming against the outer extreme ends of the respective plates 30 and 31 swinging the body 40 of the clamp inwardly toward the body 25 of the heel 24 and bringing its flange 41 over the felt strip 52 as shown in Fig. 5. Continued inward swinging of the finger 47 forces the body portion 40 downwardly bringing its flange 41 into tight gripping and interlocking relation with the felt strip-52 andwvedging the "curved-portion- "44 "of the strap 42 between the wall edges of the slot 35 of plate 30 as shown in Fig. 5, the finger 47. rnov-it1 g into locking position o'ver'f-the' curved portion #4 of the strap with the pointed edges49' of the ears 48f pressed against: the" respective' plate,su'ch as plate3'0 as shown in Fig.3; This securely locks the clamp in position andtsecurely fiXcs the h'e'elon the shoe. 7 p

In the modified form of frame shown'inF-ig. it), the connectin p'latesi32', 32hr the fo'r'r'n of Figs. 1 m9, incl'usiveare omitted and: the enter strap-or plate 27' is formed with end extensions '60for connecting, the plates 30' and131'. In all otherrespects, the form or frame shown inFig; IOissi""'l' tothe'i form shown in Figs. 1 to 9, inclusive, and s'im arv reference numerals are used to indicate simfil'a'r 'p'artsjther'eof.

Iii the modified for of clamping device shown in Figs. 11 and 12,,the upwardly overlapping extension 44" or the strap portion 42" of the'clarnpihg body 40" is slightly bent instead of beingcurv'e'd as in the torr'nof Figs. 1,10 9, inclusive. 'Thefing'er' member- 47 of the latching device is also inwardly bent instead of being curved and isformed with a semi-spherical detent member 65 on the outer surface of its free end. A latch member ddpivoted at one end on a pivot pin 67 extends thronghthe overlapping extension 44 and is formed with a1hool'c'68 at its other end having an opening "69 therein adapted to seat yieldingly on the detent member 65 whenth'e lat'chinember is swung to operative position as shown inFigs. 11 and 12. The latch member 366 is shown in unl'atche'd position in dotted lines in Fig. 11.

In all otherrespects the clamping device of Figs. 11

and 121's similar to fthe clamping "device shown in Figs. 1 t'o9, inclusive, andsirnilar reference numerals are used to indicate similarparts.

' The modified form of clamping device shown in Figs. 13 to 15, inclusive, ditf'ersfrom. the form shown in Figs. llandv 12 in that the latching'inember comprises a sleeve 70slidably mounted on the overlappingex'tension 44" and has a hook 71,formed on thefront' of. its upper edge adapted to interlock with the top end 'of theifinger 47". Aprotuberance 7 2 on the .top end of the overlapping extension 44; limits the upward movementtof thesle'e've 70. vThe latching sleeve 70 is shown in unlatchingposi-' tion in dotted lines in Fi'g.'14.
